Миниатюрный ограничитель перенапряжения Ewimar PTF-51-PRO/POE/MICRO для защиты сети

PTF-51-PRO/POE/MICRO – Miniature surge arrester for network protection The PTF-51-PRO/PoE/Micro v2 surge arrester is a modern device that effectively protects 100-BaseT LAN networks. Thanks to the use of UTP category 5 and 6 cables, this miniature arrester is an excellent solution for those seeking reliable protection against surges and lightning discharges. Its compact dimensions allow for easy installation in small enclosures, making it an ideal choice for IP surveillance cameras and other sensitive end devices. Compact design and easy installation The PTF-51-PRO/PoE/Micro v2 features small dimensions, which facilitates its installation in various locations. The built-in cable with an RJ-45 plug makes installation quick and hassle-free. This allows the arrester to be discreetly placed in enclosures, enabling a neat finish to the entire installation. Protection against surges and lightning discharges The device effectively protects against the effects of surges, eliminating voltages above 3.5V on each transmission pair and discharging loads to ground up to 2kA. Version 2 has been designed to increase the level of protection and improve mechanical properties, making it a reliable solution in demanding conditions. Application in PoE and LAN systems The PTF-51-PRO/PoE/Micro v2 arrester is ideal for installations in PoE systems, where it provides protection against voltage increases on power lines. With compliance with IEEE 802.3af/at/bt-type 3 (HiPoE, UPOE) standards, the device is suitable for switches and IP cameras that may be exposed to surges. High protection performance for external devices The arrester is recommended for use outdoors, where there is a risk of sparkover or large induced loads in the cables. It is important to connect it to ground or the PE protective conductor, which provides additional safety. Thanks to its IP54 enclosure sealing and wide operating temperature range (-30ºC~60ºC), the device will perform well in various weather conditions.
